▪ Storage volume is striped across
hundreds of storage nodes distributed
over 3 different availability zones
▪ Six copies of data, two copies in each
availability zone to protect against
AZ+1 failures
▪ Plan to apply same principles to other

maximum read replica lag across 4 replicas never exceeded 20 ms.”

TRADITIONAL APPROACH AMAZON AURORA
Maintain a buffer of log records to write out to disk
Issue write when buffer full or time out waiting for writes
First writer has latency penalty when write rate is low
Request I/O with first write, fill buffer till write picked up
Individual write durable when 4 of 6 storage nodes ACK
Advance DB Durable point up to earliest pending ACK
Re-entrant connections multiplexed to active threads
Kernel-space epoll() inserts into latch-free event queue
Dynamically size threads pool
Gracefully handles 5000+ concurrent client sessions on r3.8xl
Standard MySQL – one thread per connection
Doesn’t scale with connection count
MySQL EE – connections assigned to thread group
Requires careful stall threshold tuning

Real-life data – gaming workloadAurora vs. RDS MySQL – r3.4XL, MAZ
Aurora 3X faster on r3.4xlarge
Recent Performance Enhancements
Faster index build (Aug 2016)
▪ MySQL 5.6 inserts entries top down into
the new btree, causing splits and lots of
logging.
▪ Aurora builds the leaf blocks and then the
branches of the tree (similar to MySQL
5.7).
• No splits during the build.
• Each page touched only once.
• One log record per page.
2-4X better than MySQL 5.6 or MySQL 5.70

Highly contended workloads had high memory and CPU
▪ 1.9 (Nov) – lock compression (bitmap for hot locks)
▪ 1.9 – replace spinlocks with blocking futex – up to 12x reduction in CPU, 3x improvement in throughput
▪ December – use dynamic programming to release locks: from O(totalLocks * waitLocks) to O(totalLocks)
Throughput on Percona TPC-C 100 improved 29x (from 1,452 txns/min to 42,181 txns/min)

▪ Accelerates batch inserts sorted by
primary key – works by caching the
cursor position in an index traversal.
▪ Dynamically turns itself on or off based on
data pattern
▪ Avoids contention in acquiring latches
while navigating down the tree.
▪ Bi-directional, works across all insert
statements
• LOAD INFILE, INSERT INTO SELECT, INSERT

Spatial Indexes in Aurora (Dec 2016)
Z-index used in Aurora
Challenges with R-Trees
Keeping it efficient while balanced
Rectangles should not overlap or cover empty space
Degenerates over time
Re-indexing is expensive
R-Tree used in MySQL 5.7
Z-index (dimensionally ordered space filling curve)
Uses regular B-Tree for storing and indexing
Removes sensitivity to resolution parameter
Adapts to granularity of actual data without user declaration

Smart selector: Aurora reduces read latency by
selecting the copy of data on a storage node with
best performance

• Other ADD COLUMN operations
• Nullable and not null columns
• With and without default value
• At the end, or in any any

Time
• Take periodic snapshot of each segment in parallel; stream the redo logs to Amazon S3
• Backup happens continuously without performance or availability impact
• At restore, retrieve the appropriate segment snapshots and log streams to storage nodes
• Apply log streams to segment snapshots in parallel and asynchronously
Traditional Databases
Have to replay logs since the last
checkpoint
Typically 5 minutes between checkpoints
Single-threaded in MySQL; requires a
large number of disk accesses
Amazon Aurora
Underlying storage replays redo records
on demand as part of a disk read
Parallel, distributed, asynchronous
No replay for startup
Checkpointed Data Redo Log
Crash at T0 requires
a re-application of the
SQL in the redo log since
last checkpoint
T0 T0
Crash at T0 will result in redo logs being
applied to each segment on demand, in
parallel, asynchronously
Instant Crash Recovery
Survivable Caches
We moved the cache out of the
database process
Cache remains warm in the event of
database restart
Lets you resume fully loaded
operations much faster

Availability is about more than HW failures
You also incur availability disruptions when you
1. Patch your database software
2. Modify your database schema
3. Perform large scale database reorganizations
4. DBA errors requiring database restores

Zero downtime patching – current constraints
• Parameter changes pending
• Temporary tables open
• Locked Tables
We have to go to our current patching model when we can’t park connections:
• Long running queries
• Open transactions
• Bin-log enabled
We are working on addressing the above.
• SSL connections open
• Read replica instances
Database cloning (planned for May 2017)
Create a copy of a database without
duplicate storage costs
• Creation of a clone is nearly
instantaneous – we don’t copy data
• Data copy happens only on write – when
original and cloned volume data differ
Typical use cases:
• Clone a production DB to run tests
• Reorganize a database
• Save a point in time snapshot for analysis
without impacting production system.

What is database backtrack ? Planned for June 2017
Backtrack quickly brings the database to a point in time without requiring restore from backups
• Backtracking from an unintentional DML or DDL operation
• Backtrack is not destructive. You can backtrack multiple times to find the right point in time.

Time
▪ Take periodic snapshots within each segment in parallel and store them locally
▪ At rewind time, each segment picks the previous local snapshot and applies the
log streams to the snapshot to produce the desired state of the DB
Storage Segments
Logs within the log stream are made visible or invisible based on the branch within the LSN
tree to provide a consistent view for the DB
▪ The first rewind performed at t2 to rewind the DB to t1 makes the logs in purple color invisible
▪ The second rewind performed at time t4 to rewind the DB to t3 makes the logs in red and purple invisible
